I have a completely stock 914-6 - weber carbs. When the engine is cold the car idles about 900 RPM. As it heats up the idle speed increases until it is idlying at about 1700 RPM when fully warmed up. It starts and runs fine. Just the high idle. Ambient temperature is currently around 85 degrees.
Since it is temperature related I'm currently thinking mabye a vacuum leak...loose manifold bolt. Any ideas on this one? Ken Schipper |

mine does the same thing but more like 1400, sometimes comes down by itself. I know the advance on these car is really touchy so if your idle goes up and timing kicks in it goes up even more, its a fine line. I do wish a weber expert could comment.
